 determine a video merging result of the physical display device as a screen capturing result in response to the value of the flag bit of the first category of virtual display device being the preset value, wherein the video merging result of the physical display device is directly used as the screen capturing result, so that video merging is not performed on the first category of virtual display device, 
 wherein the display device list further comprises a second category of virtual display device, and the processor is further configured to: 
 identify whether a value of a flag bit of each display device among the physical display device, the first category of virtual display device, and the second category of virtual display device included in the display device list is the preset value; and 
 in response to the value of the flag bit of any one display device not being the preset value, perform video merging on the any one display device to generate a video merging result of the any one display device. 
 
     
     
       9. The electronic device of  claim 8 , wherein the processor is further configured to:
